Orchid Fahrenheit Settings Please

[David Davies]

I have an Orchid Fahrenheit 1280 isa graphics card, bios ver 2.00, 1mb VRam.
Can anyone tell me the settings for the set of 4 dip switches and the 2
jumpers on JP2. JP1 is IRQ9 and JP3 is for 512k or 1mb video memory ( beacause
they are marked). I am trying to put it in another machine and it doesn't like
it much.
I was working okay when taken out of another machine but one of my
family decided to play with the little switch things :-)

Any help gratefully appreciated.

TIA

I have a Fahrenheit 1280 D (the local bus version) but the book covers both.
